In this paper, a novel CoPlanar Waveguide (CPW) fed dual band-notched Ultra-WideBand (UWB) antenna with circular slotted ground is proposed. In order to achieve two notched bands at 3.3-3.7GHz for Worldwide interoperability for Microwave Access (WiMAX) and 5.15-5.825GHz for Wireless Local Area Network (WLAN) respectively, a pair of bended dual-L-shape branches is attached to the slotted ground. By optimizing the lengths and positions of the branches, the desired notch-bands of WLAN and WiMAX can be achieved. The prototype of the proposed antenna was fabricated and tested. The simulated and measured results show good agreement over the ultra-wideband.
